Numerical methods for two- and three-dimensional viscous flows

An overview of the main options available for the application of finite-difference methods to two- and three-dimensional recirculating flows, either laminar or turbulent is presented with attention focused on the alternative paths that can be chosen for the solution of the discretized Navier-Stokes equations. The merits of basin methods on the use of density as a main dependent variable in preference to the pressure are examined and techniques based on the use of the pressure are discussed, within the context of practicability and generality of application to engineering problems. Where possible, recommendation of certain choices are made. Sample calculations carried out for a variety of two- and three-dimensional flows are presented.
